Title: Television screen protector
Inventor: JOHNSON BRIAN A
IPC: H04N5/64
Filed: 2009-02-09
Abstract: The three (3) types of televisions available today include liquid crystal display (LCD), Plasma, and cathode ray tube (CRT). LCD television relies on a fluorescent back light that illuminate liquid crystals via an electrical impulse to make the picture. Plasma televisions use millions of pixel cells which are excited by electric pulses and produce natural gasses which cause them to glow, and produce light, which results in a picture. The cathode ray tube (CRT) television is a vacuum tube containing an electron gun and a fluorescent screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen.  The screen surfaces in televisions are susceptible to damage from direct contact, of various forces, from many sources. The damage can range from light scratches on the screen to the complete destruction of the display surface. The cost to repair the televisions can go as high as to exceed the replacement cost of the television.     This invention, television screen protector, protects televisions from damage due to contact with the screen from various causes/sources, and keeps the television screen clean. The protective barrier in front of the screen provides a surface to absorb, and disperse the force of contact from various sources, without damaging the television screen.
